Re: 431RWHP A4 346 Conrats to Tom and LS1Speed - great numbers. I've been by Tom's shop a few times when I lived in Chicago and actually met Tom. He seems to be a down to earth, no-nonsense kinda guy. If I still lived up there, LS1Speed would be performing my go fast mods.

Re: 431RWHP A4 346" Thanks for sharing Speed Inc.!
The cool thing about when they post dyno numbers they install so many different combinations of heads and cams that we get a lot of fair and unbiased numbers off that dyno.

Re: 431RWHP A4 346" Just goes to show Speed Inc rules. 
Only had a few things installed by them but very happy with there service. Getting a appointment is another story. You guys are too good and busy. 
Can you use those heads with that cam on a stock short block? Im planning on heads and cam first then your 346 shortblock later. But before that im gonna have to have you guys get me a new 4L60E my stocker is going south fast.

Re: 431RWHP A4 346" The heads/cam will work with your stock shortblock just fine.
